TER changed
Many people recognized the new conditions for uploading extensions into TER. You always have to set the dependencies to an actually supported TYPO3 version.
This is a good thing to hide extensions which will not maintained any more.
But also the upload changed...
TYPO3 >= 6.0
In TYPO3 >= 6.0 you will miss the "Upload to TER" possibility in the Extension Manager. The EM is completely rewritten and many things like the language and the TER upload part were pulled out of this extension.
You can see a new language module in the Backend, but what about uploading an extension?
The new CLI support
Honestly, I don't know who was the first. Two people are maintaining a CLI tool for e.g. uploading extensions to TER. The results of Tobias Liebig [1] and Elmar Hinz [2] can be found on GitHub.
This tool is really easy and awesome, because you get more information on what happened if an upload fails.
But you have to pay attention about the process before uploading. In EM <= 6.0 you could select the target version of your extension.
If you upload by CLI you have to set the target version of your extension in the ext_emconf.php by yourself. Otherwise you overwrite your current version.
Maybe someone can get a hand on this to improve the CLI script. But for a fast and easy solution, this is my favorite.
Extension upload within TYPO3
Months after the release of TYPO3 6.0 Georg Großberger released the extension "extension_uploader" [3] which handles the TER upload within the TYPO3 Backend.
I have not uploaded an extension with it yet, but for people with no possibility for CLI usage or lovers of the easy handling in the TYPO3 Backend it is a good alternative.
There you can not only set a bugfix, minor or major release, even a custom release number can be set!
A very cool feature would be a nice possibility to set the TYPO3 version dependency without editing the ext_emconf.php
